Last Answer : (1) Epistasis Explanation: Epistasis refers to the phenomenon in which one gene hides the effect of the other. In other word, it does not allow the other gene to express itself. This is counterpart of ... may be in one direction only meaning that ei-ther A hides the effect of B or vice versa.
